Abstract

In glaucoma there is progressive death of the retinal ganglion cells and axons. The highest density of retinal ganglion cells (RGC) lies at the macula1 and damage to the macula has now been shown to occur early in glaucoma.2 On standard automated perimetry, the macula is represented within 10 degrees of fixation. The traditional 24-2 visual field (VF) strategy tests only 4 points in this region, while the 10-2 strategy tests 68 points. The 24-2 test has previously missed VF defects that were detected using 10-2 test.3 Quality of vision, and invariably quality of life for glaucoma patients can be adversely affected if macula damage is overlooked because functionally, the macula is key to daily tasks like reading, driving, and contrast sensitivity. The aim of this study is to determine patterns of VF defects of this vulnerable macula using the 10-2 VF strategy in Africans with early to moderate primary open angle glaucoma.
